Abstract
The numerical finite-size technique has been applied to study thermodynamic properties of the S = 1 quasi-one-dimensional magnets CsNiF3, (CH3)4NNiBr3 (TMNB), (CH3)4NNiCl3 (TMNC) and CsNiCl3, the latter showing the Haldane gap. The length of chains has been extended up to N ≤ 8 and the successful fitting procedure has been performed to match the parameters of the easy-plane Heisenberg model with single-ion anisotropy. The quantitative agreement with experiment has been found both for the zero-field and the field-dependent properties. An attempt to apply the renormalization-group approach is also put forward for CsNiCl3. © 1992.
